Answer 1

Though I have done this several times, sending email through another provider is always a painful task.

Though this maybe ok,

$config['newline'] = "\r\n"; //use double quotes

but, Sending email with gmail smtp with codeigniter email library suggests

$this->email->set_newline("\r\n");

Also are you sure you allowed less secure apps in gmail?
